Roman Storm is a software developer and co-founder of Tornado Cash, an Ethereum-based cryptocurrency mixing protocol. Prosecuted by U.S. authorities over the tool's use in money laundering, he was convicted in August 2025 on a conspiracy charge and has become a prominent voice in debates over developer liability for code used by others.
Prosecutors say the ruling upholding Bitcoin Fog's founder makes one Tornado Cash user's Manhattan transactions enough to try Roman Storm in New York. If Judge Katherine Polk Failla agrees, a mixer developer could be tried wherever one user deposits into the pool.
FinCEN withdrew its proposal to make about 15,000 institutions report foreign crypto mixer transactions, work it estimated at 1.47 million hours a year. Banks keep their general duty to report suspicious activity, so mixer exposure stays a monitoring job without its own form.
Aztec Labs is bringing back zk.money as a private DAI wallet that caps every transfer at $2,500 and all users' deposits combined at $50,000 a day. Raising either limit means a new contract that each user must opt into. The caps arrive while US law on privacy wallets remains unsettled.
The judge moved the second trial to April 26, 2027, on the defense's own request. The count that would actually settle non-custodial developer liability is still waiting on sentencing.
Roman Storm says the theory that convicted him would also reach Google and OpenAI. It is a post, not a brief, and the count he was convicted on is the one his analogy fits worst.
